    What are the advantages of a solid seat pan?

    Hi All,

    I am starting to fill in an order form for a new TiLite ZR2 for my son and one thing puzzles me (and the UK rep. who can see no clinical advantage) Can anyone tell me what advantages, clinical or otherwise, a solid seat pan like TiLite's G10 has over a canvas sling?

    Does anyone know if I ordered a canvas sling I could retro-fit a CF seat pan or would that require drilling and tapping the seat frame?

    Thank you,

    Curly

    dont know about the retro fitting etc. BUT i am a firm supporter of solid seat pans and will probably never be without one. i am sitting on my first solid seat with my Marvel M1 chair i am and very pleased in the differnce. they do add a little weight but they outlast expensive canvas seat slings that i used to routinely replace at least once a year. no more sag issues with a seat sling & cushion for that matter making seating much more comfortable. i would suggest if he has a sensation feeling bottom to get a slightly thicker daily seat cushion as the solid pan is harder........good luck in making the decision

      I've been using a solid seat pan for about 10 years. I switched because I was tired of sagging bolt-on slings that were a pain to re-tighten. (This was before the adjustable strap versions came to market.)

      I immediately liked the improvement in my posture, sitting taller in my chair. Some people, however, feel (or fear) that with a solid pan they're sitting on the chair rather than sitting in the chair. A seat sling gives the user more seating set-up choices with the obvious exception of the experience of sitting on a solid base.

      If you order a bolt-on sling there should be no problem in retrofitting a solid pan, though a solid pan doesn't require as many attachment points (my ZR is secured with a total of 6 screws -- 3 per side).

      I also prefer the aesthetic of it and the simplicity to keep it clean. But more than anything else, I think it promotes better posture -- for me, anyway -- and over many years sitting in a wheelchair, that's not insignificant.

        While I have not used a solid seat pan, I wish I would have ordered one in my new chair. In my new chair I purchased the strap adjustable seat upholstry and while I do prefer this over the standard upholstry seat, only because I can keep it tight, it is a bit of a nuisance because I must tighten it regularly; I have come to learn, for me, when the seat upholstry starts to sag it causes me a lot of pain in my lower back and legs. A solid seat pan would eliminate the issue.

        That said, I would probably spec my chair a bit differently in doing so, I suspect, going down a half inch in the rear.

          I like the non-stretchy firm feeling of a solid seat. I also like the light weight of a fabric seat. I think Lasher's racing sail cloth is the best. Uber-light and doesn't stretch, a bit. After ~2 years of daily use the cloth seat and back on my Mg haven't stretched even one little bit. It's the best upholstery I've seen on a chair so far. I'm going to transplant it onto all my future chairs.

              My newer chair is my first experience with a solid pan, and I like it very much. I feel that my transfers are easier because there is a solid surface with none of the metal tube movement to be found in sling seats. It keeps my hips from rotating in ways they were not meant to rotate too.

                I find a solid seat pan more stable and honestly more comfortable with the cushion on top. Better posture too.

                  I copied this quote from my post in another similar thread (https://www.carecure.net/forum/showt...ighlight=apple).

(I'm not sure how it compares to carbon fibre though, but is bound to be way cheaper). I was willing to pay the money for other more expensive options so I don't think he was trying to steer me in another direction for his benefit.


                  Why don't you try putting a thin piece of plywood inside his cushion cover to see if he likes how it has him sitting. If it is better then you can make a more informed decision on whether or not to get a solid seat pan..

                    I had a friend make me a wood insert to try inside my cushion, the problem was, which I expected, it caused me to sit higher than I wanted; if I could lower my rear seat height I may have been fine with it.

                      Yeah, we knew we were going to do this when we were demoing chairs so we did account for it. It worked out ok but in the end I still would have liked if my chair was about 1/2 an inch lower rear seat height. Not a major problem but I would have liked to have the option to try the lower height to see if I liked it better.

                      That is why I would probably lean towards a ZRA instead of a TR if I was able to order again. Overall I like the TR better but ordering a chair and a cushion, especially Ride Designs or other custom cushion at the same time can lead to unexpected seating positions. Or I would order the cushion, get a demo ZRA and experiment until it is set so the all the dimensions felt right with the cushion and then use those measurements to get a TR set up the same way.

                        primarily better posture... keeps hips from internally rotating too.

                          other then the above mentions crappy piece of wood that they charge you $70 for I haven't had a solid seat pan. I hate the seat sling and how it causes bad posture due to sinking between the two polls.

                            I have an ADI Carbon Fiber solid seat pan on my TiLiite ZR and it has improved my posture without adding too much weight. With a flat bottom seat pan, you don't have to worry about your positioning as much as a sling bottom. The sling bottom tends to stretch out and will curve slightly causing improper seating position when you aren't centered. I also have less back pain now, I suggest getting one.

                              benefits of a solid seat pan

                              Thanks to all members who took the time to express their thoughts on this subject, I found them all really useful. I have subsequently spoken to a TiLite rep. in the UK and he was of the opinion that as my son has Muscular Dystrophy and not a SCI the benefits may be minimal but even he couldn't say for certain. I think we'll opt for the canvas seat pan attached by bolts and then maybe go for an ADI CF seat pan at a later date if our son thinks it may benefit him, that way we can use the bolt holes for the solid seat pan.

                              Once again, thanks to all members who have helped.
